Collection 8/15/57/8 - granular conglomerate bed which forms nose of anticline at the joint road cross it. About 100' stratigraphically below #7. {note: illustration followed} PG. 35 8/16/57 - Neal Ranch Studied the face of #2 gray limestone member of King. Collection 8/16/57/1 - near base of reef rubble beds west of west reef in main massif. This as a mirror image, the view is really east, {note: illustration: bed 1: Covered bed 2: 10'; coarse rubble bed 3: 8'; 8/16/57/1; irregular bedded fine rubble bed 4: 55' massive; 8/16/57/2 bed 5: 10'; crude bedding but indistinct} 8/16/57/2 - boulder from higher in the reef. 8/16/57/3 - just below notch in #2 limestone mbr. North of Neal Ranch. 3 bags; This collection is from reef talus beds and is really loaded with fusulines (for reef strata). PG. 36 8/16/57/4 - on west flank of east massif on main reef, this was collected about 20' stratigraphically below a brown weathering dolomite bed 7' thick. {note: illustration: 8/16/57/5 Dolomite 8/16/57/4 Notch} This has a fairly rich fusuline fauna. Collection 8/16/57/5 - about 10' above dolomite bed. This has a few fusulines, but several (at least 2) kinds of Ceratitic ammonites. Collection 8/16/57/6 - East side of geologists' canyon above terrva block structure in what is fairly definitely Gaptank if King's maps are right. Collection 8/16/57/7 - shale from Uddenites zone exposed on Terrva block east of Geologists' Canyon. PG. 37 Collection 8/16/57/8- from Uddenites shale interval, east side of Geologists' Canyon, on Terrva Block I believe the actual occurrence of Uddenites is quite low in this zone. Collection 8/16/57/9 - Top bed in terrva block, east side geologists' canyon. Collection 8/16/57/10 - about same stratigraphic position as 8/16/57/9 but is on the thin wedge of #2 limestone member which pinches out on the Gaptank. {note: illustration followed}. PG. 38
